Exploring Primordial Curvature Perturbation on Small Scales with the Lensing Effect of Fast Radio Bursts
Cosmological observations, e.g., cosmic microwave background, have precisely measured the spectrum of primordial curvature perturbation on larger scales, but smaller scales are still poorly constrained. Since primordial black holes (PBHs) could form in the very early Universe through the gravitation...
